Valhalla High School says that a teenager from outside the school district joined a class on Google Meets Friday and used profanity.

The school released a statement, saying: "It was upsetting to the teachers and to the students. We believe the individual had access to the meet because one of our students gave him the meeting code."

In the statement from Principal John Hirsch, he says additional measures are not in place and he has shared them with the staff to ensure it doesn't happen again.

He says any students who share their code will face consequences. It is also a part of school policy to keep their real names on screen and their cameras during remote learning unless there are extenuating circumstances.

Experts say it's important to train teachers on how to limit access to virtual meetings and remove anyone who's not supposed to be there. They also recommend parents prepare their children for the risks that come with remote learning.

The school is also urging anyone with more information on the incident to come forward.
